You are right Graham
It was a bit sloppy wording using "many" instead of a few. I guess I was carried away when checking two units and both units were those who obviously didn't get the order to change codes...
I agree that if everone really wanted to change codes, you could repaint the aeroplanes in a couple of minutes that is if the CO and down rushed out with bucket and brush all set to do what their superiors instructed.
Somehow I cannot fancy any CO rushing out in coveralls re-decorating everyones airplanes including his own....
